Some of the common wattages vs.
100 watt incandescent light bulb vs led.
40w equals 450 lumens 60w equals 800.
Average cost per bulb.
Leds require less wattage than cfl for the same amount of light.
However because lumens per watt vary for both incandescent and led lights it s easier to use a wattage to lumens comparison chart.
Led viribright watts used.
Total purchase price of bulbs over 20 years.
It would only take a 16 watt bulb to emit as much light as a 100 watt incandescent bulb and it would use only 140 kwh of energy over the year.
Oh and one led would last the entire year.
The difference is significant especially for rvers who do a lot of dry camping.
These bulbs last longer and use up to 80 less energy reducing energy and replacement costs.
When dave connects incandescent bulbs to an amp meter they draw up to 1 6 amps but when led lights are used they only pull about 26 amps.
Life span of led vs.
A 100 watt incandescent lamp that emits 1200 lumens of light has an efficacy of 12 while an equivalent 12 watt led bulb that emits 1200 lumens has an efficacy of 100 which is more than eight times higher than incandescent so use very less electricity while emitting the same amount of light.
It simply means that the bulb whether cfl or led is able to produce as much light as a 60 watt incandescent.
Available in 40 60 75 100 watt equivalent.
Bulbs needed for 25 000 hours.
The electric cost would be just 21.
Dimmable globe led bulbs designed for bathroom vanities or anywhere a globe bulb is required these bulbs produce light equivalent to a 40 watt incandescent bulb yet only consume 10 watts of power.
While the math for the cfl bulbs is simple the led bulbs are even more energy efficient and durable than compact fluorescent light bulbs.
100 watt equal led light bulbs if you are still using 100 watt incandescent bulbs it s time to upgrade to 100 watt led bulbs.
Cost of electricity 25 000 hours at 0 15 per kwh.
Led vs cfl vs incandescent cost.
For example a correct replacement for a 60w incandescent bulb would be a 15 watt cfl bulb 60 1 4 15.
Since most household bulbs are 40w 60w 75w or 100w you may be able to memorize their equivalent lumens.
